    New Fibonacci 2.5.2

    vegan

      I have set the bar higher with the new version of Fibonacci, now that  I have 4 GB of RAM I cranked up the RAM test to make it more meaningful  for DDR3 and the upcoming DDR4 next year.

      I added a check to make sure that the user has the RAM to prevent crashing the machine,
